[Abstract]
Globally, the most talked-about topic of the 21st century is by far climate change. Since the mid-18th century, the Industrial Revolution has improved the quality of life for humankind through technological innovations. However, contaminants and greenhouse gas (GHG) emissions from fossil fuel use along with deforestation to secure fuel and arable land in many parts of the world have had a negative impact on human health and the environment. In particular, climate change caused by GHGs include temperature change, precipitation change, earlier spring snowmelt followed by increased wildfires, extreme storms and severe weather events, coastal erosion, ocean acidification, glacier melt and sea level rise ? with profound impacts on all areas of society, including water quality, air quality, energy, transportation, agriculture, and ecosystems. Transportation and electricity generation are two main sources of GHGs, followed by industrial, commercial, and residential activities, and agriculture.
A major driver to mitigate the effects of climate change is the Paris Agreement of 2015. The central aim of this international climate agreement is to hold global temperature rise in this century at less than 2°C above preindustrial levels and to pursue efforts to limit further temperature increases to 1.5°C. As part of efforts to comply with the Paris Agreement, many countries are planning to reduce the use of fossil fuels, increase the use of renewable energy, such as solar and wind power, and increase energy efficiency; in addition, some countries are constructing nuclear power plants. In Korea, the current energy policy includes reduction of coal and nuclear use and deployment of renewables and energy efficiency technologies, which is leading to draconian changes in the energy environment and many aspects of society. The energy policy established now will influence the energy environment for the next several decades to come. Accordingly, it is important to assess whether the current energy policy and planned fuel mix for electricity generation (spanning coal, nuclear, natural gas, and renewables) represents a practical approach, considering Korea’s limited energy resources such as fossil fuels, solar and wind potential and the isolated grid system inherent to its geography.
Topics covered in this seminar are:
- Background of energy use
- Definition of basic terms related to electricity generation
- Reasons why renewable energy is favored
- Electricity generation by source in Germany/U.S./China/Japan/Korea
- Types of non-renewable energy and their environmental impacts
- Types of renewable energy and their environmental impacts
- Alternative energy technologies on the offshore continental shelf
- Transmission line issues
- Demand-side management
- Summary and conclusions
